Mesosphere

The mesosphere is the third layer of the atmosphere, directly above the stratosphere and directly below the thermosphere. In the mesosphere, temperature increases with height, but the average temperat

Earth's atmosphere as it appears from space, as bands of different colours at the horizon. From the bottom, afterglow illuminates the troposphere in orange with silhouettes of clouds, and the stratosphere in white and blue. Next the mesosphere (pink area) extends to just below the edge of space at one hundred kilometers and the pink line of airglow of the lower thermosphere (dark), which hosts green and red aurorae over several hundred kilometers.

Noctilucent clouds, or night shining clouds, are tenuous cloud-like phenomena in the upper atmosphere. When viewed from space, they are called polar mesospheric clouds, detectable as a diffuse scatter
Mesosphere
…so large that the waves become unstable and dissipate. This dissipation deposits momentum into the mesosphere and largely drives global circulation. Noctilucent clouds are located in the mesosphere. The upper mesosphere is also the region of the ionosphere known as the D layer, which is only present during the day…
